Wi-Fi SD cards are kinda cool, but I don't know any pro that uses them. The write speeds tend to be slow, which is noticeable even for still photography nevermind if you're recording 4k video on a prosumour drone or camera. Secondly, they're inside a device and have the antenna built in, so as well as draining battery it's slow to transfer files off. If you're shooting 3mb jpegs then it might be OK, but my 6 year old DSLR is producing 30mb files per exposure.
